Added Moran process type and some associated methods
Added a function for selection populations from a distribution
Added a moranProcessStep! function that simulates one step of the moran process
Changed error syntax and gave errors type ArgumentError
Added some more error checking to Population type
Changed types of arguments to fitness and reproductionProbability to be reals instead of Float64s
Modified fitness and reproductionProbability functions to be parametric with respect to the type of the elements of the matrix game
Added some tests for the Population type and related methods, and added a custom error handler that gives colored output
Added a function to generate time series
Fixed miscellaneous type errors
Moved custom test handler to a different file
Mutation vector was being incorrectly calculated, leading to occaisional errors when the random number in samplefromPDF function was close to 1
Added vim swapfiles to gitignore
Added a function to generate stationary distributions
Added functions for computing stationary distribution, fixation probability and transition matrix
Converted parametric types to Reals
Reverted types for some functions to parametric, but made them subtypes of Real
Rewrote notebook to use new code
Add fitness mapping functions
Modified functions for intensity of selection mapping for better type
handling and handling of arrays
