danlwarren/ENMTools: ENMTools 1.0.1

This is the first post-CRAN update to ENMTools, which fixes a few minor issues and adds some useful new features.

• Added variable importance tests via interface with the vip package
• Added clamping for the predict functions, including plots of where clamping is happening
• Added clamping for model construction functions, with a TRUE/FALSE switch defaulting to TRUE
• Changed naming conventions for predict functions so that the suitability raster is in the $suitability slot, just as with modeling functions
• Added progress bars for a lot of tests
• Added "verbose" option for a lot of functions, defaulting to FALSE

• Added some code to fix a bug with recalibration. Basically CalibratR's call to parallel was tanking on Mac OS, and there's just a little code snippet that needed to be added to the call to make that work.
• Fixed interactive.plot generic and moved the function to its own file to make it easier to extend
• Temporarily suppressing some warnings coming out of leaflet that are being produced by the recent rgdal changes
• Fixed background sampling code to resample when necessary
• Changed enmtools.ranger demo code to actually use ranger instead of rf
• Fixed code for calculating p values for some of the hypothesis tests, the old code was getting wrong answers when there were repeated values
