I decided to remove FPCAtest.r for now. Will have to create a new pipeline package which includes all these pieces.
Bumped to version 0.4.1.
Use R function nrow() instead of the original ugly "length(x)/3" approach.
A0, b0 are in the sparse matrix form.  b0 is now a 10x2 matrix according to Leqin's new specification.
 1. Fixed a small bug, in which TIMEPOINT was called before it was defined.
 2. Use R function nrow() instead of the original ugly "length(x)/3" approach.
