Vector operations between grapes

This package contains only infix functions (grapes-function-grapes), most of them shorten the syntax for common vector operations, such as finding indices and extracting values from vectors.

The main function classes are:

• Extractors - Extract indices or values from the front or the rear of a vector
• Insiders & Outsiders - Determine whether values in a vector are inside or outside a specific range and/or exctract those values
• Counters - Automatically increment a value or a numerical object (e.g. in a while loop)
• Padders & Trimmers - Padd or Trim the front and/or rear of a vector
• Regressors - Perform simple polynomial regression on vectors

In addition, some infix functions for very specific tasks are provided, e.g., the rose tinted infix %00% provides a means to deal with functions that return NA, Inf, NULLor other error/exception values by turning them into a user specified value.
