Telodendria/configure
Jordan Bancino 1fee47a628 Use Makefiles instead of a custom script (#38)
This pull request also requires the use of the external [Cytoplasm](/Telodendria/Cytoplasm) repository by removing the in-tree copy of Cytoplasm. The increased modularity requires a little more complex build process, but is overall better. Closes #19

The appropriate documentation has been updated. Closes #18
