Outputs checkbox input element
{{{el-checkbox name=name}}}Calls handlebars.el.form~inputHelper passing checkbox as the type
Since inputHelper in turn calls the el helper, accepts any parameter that the el helper takes
Examples
{{{el-checkbox name="foo"}}}
→  <input name="foo" type="checkbox" value="true">
{{{el-checkbox name="foo" value="bar"}}}
→  <input name="foo" type="checkbox" value="bar">
{{{el-checkbox name="foo" attributes=attributes}}}
Context {attributes:{value:"bar"}}
→  <input name="foo" type="checkbox" value="bar">
{{{el-checkbox name="foo" checked=true}}}
→  <input checked name="foo" type="checkbox" value="true">
