1. Consolidated modules that retrieve data from various sources into a new directory 'import'.
2. Refactored CrunchBase data import functionality into separate modules, according to the import method (API, CSV, XLS).
3. Improved code in 'getCrunchBaseDataAPI.R', but not complete - still have problem with passing arguments iterated function through lapply (see http://stackoverflow.com/questions/12792896/passing-arguments-to-iterated-function-through-apply).
