 Continue work on getting landos to be functional.
 Continue work on getting landos to be functional.

Changes include: getting structure setup correctly, use library provided functions, fix matlab indicies, correct some places where I thought a variable was a scalar and was really a vector, fixed signature (input/outputs), slightly improve documentation.
Still untested (even checking if it compiles), but significantly closer to a working state.
