Removed Delta input arguments from many functions. Use shc_lv_neighborhood()

Also improved "See also" references in the help of many of these functions.

Fixed bug in initial condition function

The "ep" variable in the non-uniform case wasn't always being created.

Also forgot to disable the non-uniform-only setting used for debugging.

More improvements to mean period constant finding function

In non-uniform case, the optional second output, N, is now on the minimum number of passages for any node. The mean is now calculated using this same number of passages for each node.

Optional third output is now a vector or matrix instead of a cell array.

New functions to calculate period and noise magnitude based on mean period constant.

Simple functions with no input checking. These use Tau_Bar constant from shc_lv_meanperiod().
