Detailed Description

Represent a resolution and an $\eta$ range in which the resolution is valid.

Usage:: Users instantiate multiple instances of this class. For each instance users provide:

The lower limit of the valid $\eta$ range.
The upper limit of the valid $\eta$ range.
The resolution, in one of the three recognized forms:
- string encoded Vector_Resolution.
- an instance of Vector_Resolution.
- three instances of Resolution which forms a proper Vector_Resolution,

See the documentation for Vector_Resolution and Resolution classes for more details.
