Road to v2.0.0

[hyrodium]

The following is a list of changes I intended for v1.0.0. However, since that version has already been released, these changes will be targeted for v2.0.0:

• Remove gausschebyshev
• Remove besselroots
• Organize function names etc.
  • For example, FastGaussQuadrature.asy should be renamed to FastGaussQuadrature.gausslegenedre_asy.
  • They (gausslegendre_asy, gausslaguerre_asy, etc.) will be treated as 'non-exported stable API', meaning they won't be exported but are stable for use.
  • Consider adding an _ prefix for purely internal functions, such as underflow_threshold.

Removing deprecated functions and changing internal function names can all happen on 1.1

Please don't remove deprecated functions such as gausschebyshev without a breaking change, as these used to be a part of the official API. By default, Julia doesn't warn about the deprecation unless one starts it with --depwarn=yes, so this may confuse users. Is there a pressing need to remove these functions right away anyway?

That's right. But I was just planning to make this package more stable before releasing v1.0.0.

No. We can wait for agreement to remove the deprecated functions.
