README error: Function should be 'greeter' instead of 'hello' in Advanced Schematics example

[lvalentieng]

In the README, under the section "Advanced Schematics that uses templates to generate files", step 4 currently refers to a function named "hello". This appears to be incorrect. The function should be called "greeter" instead.

Under the section "Create Angular service and model using schematics", step 14 should be:

schematics .:http-resource employee --url http://somedomain.com/api/employee --find-one --dry-run false

Thank you!
