Sequence of ELM Dynamic Equations

ELM dynamic equations are implemented in a series of function calls that reside in different source code files depending on the spatio-temporal aspect of the functions.
At startup, the GenericDriver.c calls various initialization functions (e.g., alloc_memory, read_model_parameters, init_vars, read_output_parms) that are executed from different source code locations. The time loop in GenericDriver.c then initiates the following sequence of function calls, with spatial relations defined in the functions as appropriate:
