Documentation Updates & Dependency Indicators

[shane-science]

Working on gbFisher, it seems that all of the lda-soft software is apparently interlinked (e.g. gbFisher requires code files listed in other source directories of lda-soft)

Dependency issues aside (that architecture should be thought about carefully) I recommend updates to the documentation to include:

(1) instructions that clearly define the installation of lda-soft, which says you need to build the entire repository

(2) Instructions should also clearly indicate package dependencies (e.g. gsl, version, etc)

(3) In the individual documentations (e.g. for gbFisher) it should say at the top what you need to do to make the code. I tried to use the gbFisher makefile and it wigged out because it couldn't find the dependent file -- the point is you can't use the makefile as included in the src repository, so the documentation should be clear on that point

(3) I think it would be useful, if the architectural dependencies could be resolved, to only be able to use one part of lda-soft (e.g. gbFisher, without any intent of every using gbmcmc)
