Commits on Mar 7, 2019

  1. add SPARSE solver to SympySolver - resolves #26 

    -for case when ODEs are coupled & linear:
-constructs backwards Euler linear system
-solves linear system by Gaussian elimination
-declares required new local variables in each solve block
-replaces ODEs (and adds new statements) with explicit solution of backwards Euler
-optionally finds CSE (common sub expressions)
-visitor logic altered to deal with each solve block separately
-added --cse flag to sympy options to enable CSE generation
-added -v,--verbose flag to enable debug logger output
-updated README with the new flags
-TODO: check it actually works (!), add tests
