SBOLv2 Stem-top glyphs #21

This PR adds the "stem-top" class of glyphs specified in SBOL visual 2.0. This class of glyphs contains, at this moment, three types of glyphs:

  • Cleavage site
  • Biopolymer location
  • Stability element

The "top" portion of the glyph specifies one of these three, whereas the "stem" portion indicates whether the glyph refers to DNA, RNA, or Protein. These replace the previous "Ribonuclease site", "Protease site", "RNA stability element", and "Protein stability element" from SBOLv1. For more information, refer to the specification, pages 21-22, 29-31, and 44-45.

This PR defines the following new parts:

  • DNACleavageSite
  • RNACleavageSite
  • ProteinCleavageSite
  • DNALocation
  • RNALocation
  • ProteinLocation
  • DNAStability
  • RNAStability
  • ProteinStability
  • StemTop

The first 9 are self-explanatory given the specification (see example code below). The last one is a generic "StemTop" glyph where the stem and top can be manually chosen using options stem and top.

The current version of dnaplotlib includes 4 "stick figure" glyphs from SBOLv1. Three of these are redirected to the appropriate stem-top glyph in this PR (Ribonuclease, Protease, ProteinStability). The fourth one is called Ribozyme, however no ribozyme glyph is actually defined in SBOLv1 or v2. In fact, the Ribozyme part is mapped to the "RNA Stability Element" glyph from SBOLv1. I didn't know what to do with this, so rather than removing it I opted for leaving it unchanged. I can modify this if required.

As an example, the following code:

import dnaplotlib as dpl
import matplotlib.pyplot as plt

# Global line width
lw = 1.5

# Define design 1
c1 = {'type':'DNACleavageSite', 'name':'c1', 'fwd':True, 'opts':{'linewidth':lw}}
c2 = {'type':'RNACleavageSite', 'name':'c2', 'fwd':True, 'opts':{'linewidth':lw}}
c3 = {'type':'ProteinCleavageSite', 'name':'c3', 'fwd':True, 'opts':{'linewidth':lw}}
l1 = {'type':'DNALocation', 'name':'l1', 'fwd':True, 'opts':{'linewidth':lw}}
l2 = {'type':'RNALocation', 'name':'l2', 'fwd':True, 'opts':{'linewidth':lw}}
l3 = {'type':'ProteinLocation', 'name':'l3', 'fwd':True, 'opts':{'linewidth':lw}}
s1 = {'type':'DNAStability', 'name':'s1', 'fwd':True, 'opts':{'linewidth':lw}}
s2 = {'type':'RNAStability', 'name':'s2', 'fwd':True, 'opts':{'linewidth':lw}}
s3 = {'type':'ProteinStability', 'name':'s3', 'fwd':True, 'opts':{'linewidth':lw}}
design1 = [c1, c2, c3, l1, l2, l3, s1, s2, s3]

# Define design 2
c1r = {'type':'DNACleavageSite', 'name':'c1r', 'fwd':False, 'opts':{'linewidth':lw}}
c2r = {'type':'RNACleavageSite', 'name':'c2r', 'fwd':False, 'opts':{'linewidth':lw}}
c3r = {'type':'ProteinCleavageSite', 'name':'c3r', 'fwd':False, 'opts':{'linewidth':lw}}
l1r = {'type':'DNALocation', 'name':'l1r', 'fwd':False, 'opts':{'linewidth':lw}}
l2r = {'type':'RNALocation', 'name':'l2r', 'fwd':False, 'opts':{'linewidth':lw}}
l3r = {'type':'ProteinLocation', 'name':'l3r', 'fwd':False, 'opts':{'linewidth':lw}}
s1r = {'type':'DNAStability', 'name':'s1r', 'fwd':False, 'opts':{'linewidth':lw}}
s2r = {'type':'RNAStability', 'name':'s2r', 'fwd':False, 'opts':{'linewidth':lw}}
s3r = {'type':'ProteinStability', 'name':'s3r', 'fwd':False, 'opts':{'linewidth':lw}}
design2 = [c1r, c2r, c3r, l1r, l2r, l3r, s1r, s2r, s3r]

# Create matplotlib figure
f, (ax1, ax2) = plt.subplots(1, 2)

# Create the DNAplotlib renderer
dr = dpl.DNARenderer(linewidth=lw)

# Redender the DNA to axis

start, end = dr.renderDNA(ax1, design1, dr.SBOL_part_renderers())
ax1.set_xlim([start, end])

start, end = dr.renderDNA(ax2, design2, dr.SBOL_part_renderers())
ax2.set_xlim([start, end])

plt.savefig('test_stem_top.png', dpi=200)

produces the following image:


(Note that fixing issue #19, in addition to this PR, is required for this script to run in my computer).

I'm open to modify names, code organization, or other details if required.
