craftml.io is an online platform for the community to
easily create, edit, and share their CraftML models. Each model file on
craftml.io is a reusable module and has a unique identifier
for importing. For example, the model file at http://craftml.io/4yS59
is a heart, created by calebhsu. The module id
4yS59. Knowing this, we can import this model and pick a meaningful tag
name, for instance, heart, like the code below.
<!-- create a heart using the module @ 4yS59 --> <heart module="4yS59"/>
