Range ranger

This library is a WORK IN PROGRESS experiment into rust APIs for me

Range ranger is a range manipulation library supporting multiple type of ranges under a single type:

• Empty
• Continuous (containing all values between min and max)
  • Bounds can be inclusive or exclusive
  • Bounds can be finite or infinite
• Full ranges
• List of values
• Single value
• Composite ranges (Union of multiple of theses)

With support for the following operations:

• Union
• Intersection
• Difference
• Contains range
• Contains value
• Overlaps
• Simplification

The range type is an enum of all the possible range subtypes. The default behaviour for ranges constructed via methods is to be simplified and sorted but non-simplified ranges can be constructed by creating the enum members directly.

Running coverage

```powershell

Requirements

cargo install grcov to install rustup component add llvm-tools-preview

Running

./coverage.ps1 ```
