Fixed a bug for users with scipy >= 0.14

v1.2

Spectral learning for a large number of chromatin marks was reimplemented in Python using the SciPy library.

v1.1

Built upon ChromHMM version 1.10, allowing parallel computing.
Used the Chip-seq peaks following Hoffman et al. 2013's method.
Added an option "noindep" which does not assume independence of histone marks.

v1.0

Built upon ChromHMM version 1.06.
Used the Chip-seq peaks produced by the program Scripture (Guttman et al. 2010).
