c#: Add ToString() implementations for compiled bond objects

[mgrandi]

Bond version: 10.0.0

it seems that when compiling bond objects for c# (and possibly other languages) that there is no ToString() override, so when printing out a bond object in a logger, it just prints the object's name, which is not desirable.

Example:

PS C:\Users\mgrandi\Downloads\gbc-10.0.0-amd64> cat C:\Users\mgrandi\Temp\record.bond
struct Record
{
    0: string Name;
    1: vector<double> Constants;
}
PS C:\Users\mgrandi\Downloads\gbc-10.0.0-amd64>
PS C:\Users\mgrandi\Downloads\gbc-10.0.0-amd64> .\gbc-10.0.0-amd64.exe c# C:\Users\mgrandi\Temp\record.bond
PS C:\Users\mgrandi\Downloads\gbc-10.0.0-amd64> ls

Adding this sounds reasonable at first blush. A design before implementing would be appreciated. Some questions that I foresee needing to address at the design stage:

• How are collections handled?
• How is inheritance handled?
• How do type converters come into play?
• What if someone wants to customize/override the generation/library's ToString implementation?
• Is there a way to add this in that doesn't break existing users that have manually implemented ToString? (The generated classes are partial.)
• An initial proposal for what a ToString representation of a Bond object should look like. Is this representation parsable? Roundtrip-able?
