[knowledge of Romanian is NOT needed for this task]
Create a new Scribunto [1] module that, given the number of elements and a second parameter (the singular of a noun) returns the correct plural form.

The plural rule for Romanian is: (n==1 ? 0 : (n==0 || (n%100 > 0 && n%100 < 20)) ? 1 : 2);

In this equation:

• n is the number of elements (the first parameter of the function)
• 0,1,2 (the possible results of the expression) are the plural forms to be used:
  • 0 means singular (return the second parameter)
  • 1 means the first plural form is used; this form will be retrieved from a Lua table. If the singular form is not in the table, it will be generated by appending 'i' to the singular form.
  • 2 means the second plural form will be used; this form is created by concatenating the word 'de ' (plus whitespace) + the first plural form

Example (use this for testing your page):
Singular: 1 locuitor
1st plural: 15 locuitori
2nd plural: 23 de locuitori
Plural table:

  plural = {}  
  plural["locuitor"] = "locuitori"

Other notes:

• in order to be seen as a Scribunto module, the script must be in the "Modul:" namespace; we strongly suggest using "Modul:Plural" [2]; if not, please mention the title used
• you will need to create a page that will invoke [3] the module in order to show it works
