Signal overwrite/send block that does not require a socket connection

[dhblum]

This issue is to add signal overwrite and send blocks that do not require a socket connection, as described in ibpsa/project1-boptest#15. This is an alternative solution implementation to #926.

[dhblum]

The private parameter names should be changed to boptestOverwrite and boptestRead. See ibpsa/project1-boptest#20.

@dhblum Should the overwrite block be merged to the master or is it not yet stable?

[dhblum]

@mwetter The block is not yet stable. To do:

• Add enumeration parameter for KPI keywords (Javier helping to complete)
• Add string parameter for variable description
• Add documentation, which includes adding unit, min, max as attribute to read.y or overwrite.u.
• Change color to white (extend continuous block instead of sample block)
• Save as separate files

[javiarrobas]

@dhblum and @mwetter,
The enumeration of the KPI signals has been merged in #1116. So far we are using entries for power and energy because we wanted the emulator developer to decide where to integrate: in the model or in the KPI calculator in python. However, I find that misleading and prone to errors in the tagging and the KPI calculation processes.
For instance the computation of cost and emissions requires power signals since prices and emission factors can vary over time whereas with an energy signal the information of when the energy was consumed is lost.
What do you think? should I leave the energy signals out and compute everything from powers?

@mwetter I've added documentation, reference results, and other needed changes for this branch, though the unittests still seem to be failing on travis and I can't figure out why. Can you please take a look at let me know what seems to be the issue?

@dhblum
the problem is that package.order is incorrect:

# Check for package.order to be up to date
(cd  ../../../../IBPSA; \
	  python -c 'import buildingspy.development.refactor as r; \
	  r.write_package_order(".", recursive=True)'; \
	  git diff --exit-code . )

You can fix it by running locally

cd  ../../../../IBPSA; \
	  python -c 'import buildingspy.development.refactor as r; \
	  r.write_package_order(".", recursive=True)'; 

and commit the updated files.

Thanks @mwetter this worked.
