Multiple indexes, multi column indexes

[Jax-p]

As long as commit #26 allows you to create other Indexes aside Primary Key it doesn't allows you to create multiple indexes and indexes over multiple columns.

Multiple indexes:

old behavior (bug?):

Because of find() in model.ts found on row 46 only one column can be unique (or have a same index). Another definitions will be ignored.

new behavior

Every defined index will be used. It uses filter() and is iterating through the whole array of indexes instead of taking only first index.

Multicolumn indexes

You can create separate index for multiple columns.
For example: If you want to create unique combination of username and email, you can define it in your model:

@Index({ type: IndexType.UNIQUE, columns: ["username","email"] })
public myIndex!: Index;

Common improvments

• indexes now labeled as a index (indexes) instead of key (keys)
• defined interface for index Index
• defined index type enum IndexType
• defined index list with SQL translation columnIndexesList
