Convert tweets to LDA-C form for using David Blei's LDA and turbotopics code

• Reads in a file into R

• Uses LDA package to convert to DTM

• export to the specific format required by Blei as per his README: http://www.cs.princeton.edu/~blei/lda-c/readme.txt:

  [M] [term_1]:[count] [term_2]:[count] ... [term_N]:[count]

where [M] is the number of unique terms in the document, and the [count] associated with each term is how many times that term appeared in the document. Note that [term_1] is an integer which indexes the term; it is not a string.
