Let's say I just created a new Field for the Asset entity.
I called that Field as "My Own Custom Field". And I chose "File/Link" as its Field Type.
Later I decided to rename this "My Own Custom Field" field to something more meaningful: "Path to local frames" for example.
How can the custom Entity's fields be renamed, edited or deleted.
How to query the Type of the Field after it was created (to verify the field stores the Number and not the Text for example)?
