Detailed Description
An if statement in Bash++.
This entity gets pushed onto the entity stack when an if statement is encountered in Bash++ code. It contains a vector of conditional branches, each of which contains a condition and a branch of code
The reason this requires its own entity type is similar to the reason for bash_while_or_until_loop: The conditions for the if statement may contain references which need to be resolved, And the pre- and post-code for those references need to be added in specific places in the compiled code.
In the case of 'if' statements, the pre- and post-code is added before and after the entire if statement. If these were parsed without their own entity type (e.g., just using a bpp_code_entity), the pre- and post-code would be added before and after each individual conditional branch, which is incorrect.
The 'bash_' prefix signifies that this is used to parse ordinary Bash code, not anything specific to Bash++
