Detailed Description

Represents a location in source code, as a range starting at a line and column and ending at some other line and column of some file.

Lines are 1-indexed, meaning a line number of 0 as either the beginning or end represents an unknown location. The range is inclusive, meaning a location representing just a single character would have its begin line and column be equal to its end line and column. There is no way to store a location representing "zero characters".

Create a new location representing the "union" of two locations.

The new location will have the beginning line and column of whichever location has a beginning earlier in the file, and an ending line and column of whichever location has an ending later in the file.
