File handling, maths, randomization, miscellaneous.
INCLUDING:
  * general maths (most functions support both scalars and list/array-likes)
  ** factorials
  ** fast sum of series 1,2,3,4,5 ... N
  ** number of sequences of N size taken from a set of K size
  ** number of places a sequence of length N can be subdivided
  ** round N to nearest power of B
  ** convert a power of B, N, to an exponent of B, such that B**E == N
  ** find common denominator
  ** find all integers that divide evenly into N
  ** linear/spline interpolation of a 1d series of values
  ** binary representation of a number
  * spatial maths
  ** subclassable Grid type
  ** grid snapping and 'is-in-cell'
  ** polar/cartesian transform
  ** polar distance
  ** calculate triple of weights based on position in triangle
  * randomization
  ** return true P% of the time
  ** weighted sampling from a set of items
  ** fill weighted boxes in a roughly even way
  ** randomly dispense contents of a box
  ** convert nested percentage weights to flat 0..1 weights
  ** dice roll (single, and iterative/infinite)
  ** chain iterator, which yields values while percentage chance of success
     rolls succeed, and stops as soon as they fail.
     Like OHRRPGCE 'chain attack/ chain %' option
  * misc
  ** find numeric limits of data types (builtin types or simple numpy types)
  ** sort sequence according to template
  ** reverse of zip (flat sequence a,b,c,a,b,c,a,b,c -> a,b,c tuples)
  ** easily read every line or every byte of a file
  ** calculate minimum number of bits required to store a given integer.
  ** quickly set multiple attributes on an object
  ** Metadata class for easy management of metadata,
     with yaml serialization support.
