---This clears all keys and values from a table, but preserves the allocated array/hash sizes. This is useful when a table, which is linked from multiple places, needs to be cleared and/or when recycling a table for use by the same context. This avoids managing backlinks, saves an allocation and the overhead of incremental array/hash part growth. The function needs to be required before use.

|
---```lua
|
|
--- require("table.clear").
|
|
---```
|
|
---Please note this function is meant for very specific situations. In most cases it's better to replace the (usually single) link with a new table and let the GC do its work.
